Prep Time5 minutes
Cook Time5 minutes
Total Time10 minutes
Servings: 1 batch

Ingredients 

  • 400 grams powdered sugar
  • 60 ml water
  • 10 grams egg white powder

Equipment

  • piping bag
  • Wilton tip #2

Instructions

Before you begin

  • With these quantities, you’ll get a thick royal icing, perfect for outlining cookies and making shapes that need to hold their form.

Making the icing

  • Place all the ingredients in a mixing bowl and beat until smooth.

Adjusting consistency

  • For a thinner icing to flood (fill) inside outlines, add a little extra water. To check: scoop up a spoonful of icing and let it fall back into the bowl. If the surface smooths out in about 10 seconds, you have “10-second icing.” If it smooths out in 20 seconds, you have “20-second icing.”
  • I prefer the 20-second version because it works for both outlining and flooding. Since the edges aren’t fully set yet, the outlines blend seamlessly with the filling, leaving no visible borders.
  • In the photo of the cookies, you can see what I mean by the piped outlines - those were done with Wilton tip #2.

Tips

  • Avoid raw egg whites because of salmonella risk.
  • If you’re using two different consistencies of icing: pipe the outlines first, let them dry for a few minutes, then fill in with the thinner icing. I like to put the thinner icing in a small squeeze bottle (like one for salad dressings). Snip the tip a little wider and the icing will flow out easily. You can also spoon icing directly into the outlined areas, but that tends to get messy more quickly.
  • Now your sugar cookies are ready to turn into little works of art!
How to store
You can store the icing outside of the fridge in a piping bag or in an airtight container for about a week. Stir before using again as it might split a little.
